The purpose of this research
work was to develop innovative environmental friendly building brick and study
their performance, particularly on wetting and drying cycle. To understand the
relative significance of these results geopolymer building brick with which different
Na2O/(Al2O3+SiO2)
has been manufactured. Geopolymer
building brick has been manufactured by using highly alkaline solution
and an aluminosilicate source. During this research work, (230 × 110 × 75
mm) size building bricks were manufactured.
After 25 days of atmospheric curing, the bricks attained a crushing
strength of 10 to 12 Mpa. Then the bricks were submerged in water to observe
the effect of wetting and drying cycle on strength of brick. Results comprised
that even after 10th cycle, there is no specific deterioration in
the crushing strength of brick.
